1. Step through each of the frames using the PLAY button. Look at the range of different valves available.
2. Select 'Experiment with the valves' from the drop down menu
♦ Operate the directional valve using the arrow buttons. Watch how the valve drives the cylinder up and down.
♦ Operate the flow control valves using the arrow buttons. Watch how the cylinder speed changes as the orifice diameter changes.
♦ Stop the cylinder at mid position. Click the recirculate button above the check valves. Watch how the cylinder gradually falls without a poppet valve to stop it.
Experiment 1: Directional valves control the direction in which the fluid flows.
Question 1: What valves do you use to control the cylinder speed?
Experiment 2: Directional valves have moving spool elements that allow fluid to leak past and actuators to slowly move.
Question 2: What valves do you use to stop cylinders creeping?
